摘要：

We have studied the impact of temperature (2-30A degrees) on the efficiency of the process of coagulation of titanyl sulfate and aluminum sulfate in the weakly acid (pH(0) 6) and weakly alkaline (pH(0) 8) media. We have established a comparatively high coagulation activity of titanyl sulfate within the whole range of temperatures being studied and the absence of such for aluminum sulfate at < 5A degrees C not only in the weakly acidic region (non-optimal conditions), but at pH(0) 8.
